Check Digit Verification of cas no

The CAS Registry Mumber 4543-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4543-21:
(6*4)+(5*5)+(4*4)+(3*3)+(2*2)+(1*1)=79
79 % 10 = 9
So 4543-21-9 is a valid CAS Registry Number.
